Description

Technical Field

[0001] This utility model relates to the field of ball valve assembly technology, and in particular to a ball core positioning device for valve assembly. Background Technology

[0002] A ball valve typically includes an end cap, rubber O-ring, synthetic ring, valve body, valve stem, and ball core. After the ball valve is manufactured, these components need to be assembled using bolts to form the complete ball valve body.

[0003] The existing technology presents several problems compared to conventional methods: Current ball valve assembly typically involves manual operation. First, an end cap is placed on a workbench, followed by a rubber O-ring and a synthetic ring. Then, the valve body is pressed onto the end cap, aligning the notch of the ball core with the end of the valve stem on the valve body. Finally, a rubber O-ring, a synthetic ring, and a second end cap are placed on top, and these components are secured with bolts to complete the main assembly of the ball valve. However, manual ball core installation is difficult to perform accurately, requiring considerable time for positioning. Furthermore, the small gap between the ball core and the valve body makes it impossible for the operator to insert their hands into the valve body during assembly. Incorrectly positioned ball cores are difficult to remove, severely impacting the efficiency of ball valve assembly and affecting the sealing performance after assembly. Therefore, we propose a ball core positioning device for valve assembly to address these issues. Utility Model Content

The driven gear 640 is fixedly connected to the mounting shaft 531. By providing the flipping mechanism, the reduction motor 620 drives the connecting base 540 to rotate at a certain angle, thereby driving the clamping mechanism to rotate. The clamping angle of the clamping mechanism can be adjusted, facilitating flexible clamping operations on the transported ball core.

[0037] Working principle: During use, the operation of the control device is controlled via the control panel 120. A positioning mechanism matching the ball valve size is selected. The support plate 210 is installed on top of the mounting base 100 using the fastening bolts 220. The ball valve is positioned via the positioning seat 230. The adjusting motor 420 drives the lead screw 421 to rotate, which in turn moves the sliding block 430, thereby moving the clamping mechanism. This allows for adjustment of the clamping mechanism's movement. The clamping mechanism is moved to the ball core area via the adjusting mechanism. The rotary motor 520 drives the drive shaft A521 to rotate, which in turn rotates the rotating bracket 530, further rotating the clamping mechanism. This allows the clamping rod 740 to rotate towards the pin direction of the ball core through hole. The geared motor 620 drives the drive shaft B621 to rotate, which in turn drives the drive gear 630 to rotate. The drive gear 630 drives the mounting shaft 531 to rotate via the driven gear 640. The rotation of the mounting shaft 531 causes the connecting seat 540 to rotate at a certain angle, which in turn drives the clamping mechanism to rotate. This allows for adjustment of the clamping angle of the clamping mechanism, enabling omnidirectional adjustment and facilitating flexible clamping of the transported ball core. The drive motor 720 drives the bidirectional lead screw 721 to rotate, and the pair of sliding seats 730 on the bidirectional lead screw 721 move in opposite directions, thereby driving the clamping rod 740 to move. The clamping rod 740 clamps the ball core and accurately places it into the valve body.
